A support structure for a vehicle is interposed between a vehicle body and a vehicle part and is connected with fastening members to support the vehicle part. The support structure is made of a non-ferrous light alloy. Among connecting surfaces of the support structure to which the vehicle body and the vehicle part are connected, an electrochemical corrosion inhibitor is applied to a connecting surface that is located on a lower side, in a vertical direction of the vehicle, of one of the vehicle body and the vehicle part. The one of the vehicle body and the vehicle part corresponds to the applied connecting surface.

A gravity casting method includes: situating a molding die having a feeder portion in communication with a cavity above the cavity to a horizontal state and pouring a molten metal from a runner in communication with the cavity; putting the molding die to a state inclined at a predetermined angle during pouring of the molten metal from a stage where the molten metal is filled in the runner and prevailing the molten metal while pouring to the inside of the cavity and the feeder portion; and returning the molding die to the horizontal state after the molten metal has been poured completely, and solidifying the molten metal.
